Abstract
Catalytic purification device for purifying air or gas by heat treatment with a catalyst. The catalyst is carried on a patterned strip or membrane that is folded in accordion style, forming two groups of parallel flow channels with simple connections for incoming and outgoing flows. Good heat economy is achieved by heat exchange between the incoming and outgoing flow of gases.
Claims11
A catalytic device for treatment of gases, comprising:
- (a) a housing having first housing end and an inlet and an outlet spaced from said inlet;
- (b) a zigzag folded membrane at least partly covered with catalyst and forming a bundle with a first end and second end, said bundle having two sides containing folding lines and forming two sets of flow channels, one set on each side of said membrane, each of said sets of flow channels opening towards one each of said two sides of said bundle;
- (c) said inlet of the housing connecting to one of said sides of said bundle and said outlet of the housing connecting to the other of said sides of the bundle;
- and
- (d) a reversing chamber located at said first end of said bundle, the chamber volume being defined between said first housing end and said first end of said bundle, so that gas entering said inlet flows through one set of said channels to said reversing chamber and then through the other set of said channels to said outlet, thereby enabling heat exchange to take place between gas going towards and from said reversing chamber.
